Introduction: Obstructive jaundice is one of the most frequent symptoms of hepatobiliary disease and caused by various diseases. So, it is mandatory to determine pre-operatively the existence, the nature and level of obstruction because an ill chosen therapeutic approach can be dangerous. MRCP demonstrates details anatomy and pathology of the biliary and pancreatic ducts. Ultrasonography still remains the first imaging modality for obstructive jaundice. Hence, aim of the present study was to evaluate the diagnostic efficacy of ultrasonography (USG) against magnetic resonance cholangiopancreatography (MRCP) in obstructive biliopathy in detection and characterization in patients suspected with pancreatic and biliary system pathologies. Material and methods: This study was conducted among sixty patients suffering from obstructive jaundice of all age groups. All the patients in the study underwent ultrasonography and MRCP. The result so obtained was expressed as percentages and variables as required.
